Can someone steer me in the right direction with these? They are all quite thin, hammered and silver. My best guess to this point is: top left - Turkey; top right - Thai; bottom left - Thai; bottom right - middle eastern. thank you in advance.
Top left looks Sassanian to me. I'm no expert but bottom left looks like an Arabic dirham or imitation Bottom right looks South Asian perhaps. Could also try the Ancients forum. Example of a Sassanian coin of mine.
Upper right: Samanids, Nasr II ibn Ahmad, 914-943, AR dirham, Samarqand mint, dated AH 307 (AD 919/920). Lower left: Umayyad Caliphate, Hisham, 724-743, AR dirham, Wasit mint, AH 123 (AD 740/741). Lower right: Iran, Safavid Shahs, Sultan Husayn, 1694-1722, AR Abbasi (?), Isfahan mint, dated AH 1131 (AD 1718/1719).
